Prevalence of Blastocystis in Patients Referred to Bushehr Medical Centers and Its Relationship with Urticaria.

Objective: Recent studies determined that the amoeboid form of Blastocystis acts as a factor in stimulating the host's immune responses and ultimately results in urticaria and other skin disorders. The present study was conducted in order to determine the prevalence of Blastocystis in people referred to Bushehr city health centers and the relationship of this parasite with urticaria. Methods: Fecal samples were collected from 180 males and females referred to Bushehr health centers and a questionnaire containing demographic information was completed for each person. Samples were examined by preparing direct smear (wet mount) and then formalin-detergent sedimentation techniques. Data were analyzed using SPSS 22.0 software and chi-square test. Results: The results showed that 11.1% of cases infected with Blastocystis and 55% of patients with Blastocystis had various gastrointestinal symptoms. Statistical analysis showed that there was no significant relationship between infection with some demographic factors such as sex, age, literacy level and residence, but this was significant with some clinical symptoms such as itching and urticaria. Conclusion: Despite the existence of conflicting information and many ambiguities about the Blastocystis, this emerging pathogen is very important in terms of causing allergic and skin disorders in sufferers, therefore, it is necessary that patients with urticaria be evaluated for Blastocystis along with other diagnostic procedures and physicians should request a test before any medical intervention. Thus, diagnosis and treatment of these people can play an important role in improving the health of society.

The association between continuous metabolic syndrome score and its components with electrocardiographic abnormalities in community-dwelling older adults: the Bushehr elderly health (BEH) program.

BACKGROUND: Metabolic syndrome (MetS) known as a risk factor for cardiovascular diseases (CVDs) has developed into a major source of health issue, especially for the elderly. In the present study, we investigated the association between continuous MetS (cMetS) score and its components with electrocardiographic (ECG) abnormalities in the community-dwelling older adults. METHODS: This cross-sectional study is derived from the second phase of BEH cohort study which is conducted on individuals aged over 60 years old. Standard 12-lead ECGs were recorded and coded by qualified physicians and continuous values of metabolic syndrome risk scores (cMetS) were measured. Data regarding socio-demographic, medical history, and lifestyle variables were collected by trained interviewers. The multinomial regression analysis was used to investigate the relationship between cMetS and its components with ECG abnormalities in the included participants. RESULTS: 2426 individuals (mean age ± standard deviation: 69.30 ± 6.33 years) were included in the final analysis. Overall, 22.5% of the participants showed ECG abnormalities. Among these, 8.0% (n = 139) of participants had minor and 14.6% (n = 354) had major ECG abnormalities. In the final models, cMetS (OR = 1.04), mean arterial pressure (MAP((OR = 1.01), and higher fasting blood glucose (FBG) (OR = 1.01) increased the risk of ECG abnormalities (p < 0.05). Also, cMetS (OR = 1.05) and MAP (OR = 1.02) were associated with an increased risk of major ECG abnormalities (p < 0.05). CONCLUSION: MetS and MAP were significantly associated with ECG abnormalities. The results of the present study suggest that ECG screening in the older population with MetS could potentially help to detect those at the higher risk of CVDs.

Lactational Exposure of Human Infants to Metal (loid)s: A Comparison of Industrial and Urban Inhabitants in North of the Persian Gulf.

In this study, postnatal metal (loid)s (MLs) exposure was compared between the petrochemical and gas area of Asaluyeh (PGA) and urban area of Kaki (UA) in Bushehr province, Iran. Two hundred human breast milk (BM) samples from the industrial and urban areas were analyzed for MLs using Inductivity Coupled Plasma-Optical Emission Spectrometry (ICP-OES). Boron (B), copper (Cu), iron (Fe), and nickel (Ni) were found at the highest levels in both study areas. Adjusted multiple linear regression models revealed that the mean concentration of total MLs in BM samples collected from the PGA was statistically significantly greater than that of the UA (655.85 vs. 338.17 µg/L). Also, the mean concentrations of all detected MLs in BM samples collected from the PGA were statistically significantly higher than those collected from the UA. The hazard index (HI) of combined MLs in the PGA and UA illustrated non-cancer risk for infants. Lead (Pb) and chromium (Cr) in the PGA and Cr in the UA showed the risk of cancer. So it can be concluded that nursing infants from an industrial area are most at risk for MLs exposure during entire lactation course than those from an urban area.

The association of body composition and fat distribution with dysmobility syndrome in community-dwelling older adults: Bushehr Elderly Health (BEH) program.

BACKGROUND AND OBJECTIVE: Dysmobility Syndrome (DS) is characterized as an accumulation of clinical risk factors for functional disability, such as osteoporosis, sarcopenia, and obesity. Neurological disorders that affect the motor and sensory systems can also contribute to the condition, resulting in gait and muscle strength disturbances, as well as a history of falls and fractures. The study aimed to determine the association between fat distribution in different body areas and the odds of older adults developing DS, as there is still uncertainty about the accumulation of fat in which area is most closely linked to the condition. METHODS: This cross-sectional study was conducted according to the data from the second phase of the Bushehr Elderly Health Cohort (BEH). Dysmobility Syndrome was defined based on the co-occurrence of at least three outcomes of its criteria. Body composition was measured using dual-energy X-ray absorptiometry (DXA) and anthropometric studies. For evaluating the relationship, multivariate logistic regression and adjusted univariate linear regression were used. RESULTS: Of 2,359 who were recruited in the study, 1,277 participants (54.13%) had DS. According to the final logistic regression model in the limb region, FM and FM to FFM ratios were significantly associated with DS [OR (95%CI) = 1.04 (1.02 to 1.05), and 3.42 (1.95 to 5.99), respectively]. Also, In the trunk region, the FM and FM to FFM ratio were significantly related to the odds of DS, although this relationship was weaker than in the limbs region [OR (95%CI) = 1.02 (1.00 to 1.03), and 2.45 (1.36 to 4.39), respectively]. CONCLUSION: Our findings indicate that a higher regional and whole-body amount of fat mass rather than fat-free mass is closely linked to an increased risk of DS, particularly in the elderly population. Notably, higher fat mass in the limbs (especially in the legs) is associated with greater odds of DS, while a higher android-to-gynoid fat mass ratio is associated with lower DS risk. Screening fat mass distribution in older individuals can be a valuable strategy for promptly diagnosing DS, implementing interventions to prevent disabilities, and improving their quality of life.

The association of body composition and fat distribution with hypertension in community-dwelling older adults: the Bushehr Elderly Health (BEH) program.

BACKGROUND: A significant proportion of the global burden of disability and premature mortality has caused by hypertension. It seems that the relationship between obesity and hypertension is not only associated with excessive body fat mass (FM) but also with body adipose distribution patterns. The present study investigated the association between regional fat distribution using dual-energy X-ray absorptiometry and hypertension in older adults. METHODS: This cross-sectional study was performed using the data from Bushehr Elderly Health Program (BEH) on a total of 2419 participants aged 60 and over. Hypertension was defined as SBP of at least 140 mmHg and/or DBP of at least 90 mmHg. SBP between 120 and 139 mmHg and/or a DBP between 80 and 89 mmHg were considered prehypertension. Participants underwent body composition measurement by dual-energy x-ray absorptiometry to analyze FM, fat-free mass (FFM) in trunk and extremities composition. RESULTS: The results showed that 460 (19.02%) of participants had prehypertension, and 1,818 (75.15% ) had hypertension. The odds of having prehypertension (OR: 1.06, 95%CI: 1.01-1.12) and hypertension (OR: 1.08, 95%CI: 1.03-1.13) increased with a rise in total body FM percentage. Moreover, people with a higher FM to FFM ratio had increased odds of being prehypertensive (OR: 9.93, 95%CI: 1.28-76.99) and hypertensive (OR: 16.15, 95%CI: 2.47-105.52). Having a higher android to gynoid FM ratio was related to increased odds of being prehypertensive and hypertensive. CONCLUSIONS: This study showed that a higher body FM, particularly in the android region, is associated with higher odds of having hypertension in older adults.

A comparative monitoring of maternal and cord serum polychlorinated biphenyls levels from Iranian pregnant women between industrial and urban areas.

The aim of this study was to compare maternal and fetal exposure to PCBs in pregnant women from a petrochemical and gas area (PGA) and an urban area (UA), by the analyses of serum samples from mother (MS) and cord (CS). After liquid-liquid extracting, samples were analyzed for 12 PCBs congeners by gas chromatography mass spectrometer. Adjusted multiple linear regression models showed the mean levels (µg/L) of total PCBs in the MS and CS samples from the PGA (1.70 ± 0.81 and 1.19 ± 0.43) were significantly higher than those from UA (1.64 ± 0.75 and 1.07 ± 0.38). PCB 44 was predominant in both MS and CS serum samples, and in both PGA (0.80 ± 0.70 and 0.76 ± 0.67) and UA (0.79 ± 0.39 and 0.67 ± 0.34). A negative correlation was found for PCB 52 as one-unit increase in the cord serum levels was associated with 0.024 g decrease in newborn weight. Similarly, one-unit increase in the maternal serum PCB 18 concentrations were associated with 0.09 and 0.086 cm decrease in newborn height and head circumference. The serum levels of PCB 18 and 52 in the mothers who consumed meat and milk at least 1 meal/week were higher than these who consumed meat and milk never or less than 1 meal/month. The findings in this study indicated that higher maternal exposure to PCBs, as result of living in an industrialized area, leads to higher PCBs accumulation in cord blood, which consequently passes to the developing fetus. These events may cause harmful effects on both them in-utero and afterbirth growth and development.

Acetylcysteine in the treatment of subacute sinusitis: A double-blind placebo-controlled clinical trial.

Sinusitis is a common disease with harmful effects on the health and finances of patients and the economy of the community. It is easily treated in most of its acute stages but is associated with some management difficulties as it goes toward chronicity. Therefore, we tried to improve the treatment of subacute sinusitis by using acetylcysteine, which is a safe mucolytic and antioxidant agent. Thirty-nine adult patients with subacute sinusitis proved by computed tomography (CT) were enrolled in a double-blind, placebo-controlled trial. They received oral amoxicillin-clavulanic acid and normal saline nasal drops for 10 days and oral pseudoephedrine for 7 days. In addition, the patients received acetylcysteine (600 mg orally, once daily) in the intervention group or placebo in the control group for 10 days. A paranasal CT scan was taken at baseline and 30 days after patients finished the treatment and was evaluated quantitatively by Lund-Mackay (LM) score. Symptoms and some aspects of quality of life also were assessed at baseline and 14 days after initiation and 30 days after termination of the treatment via the Sino-Nasal Outcome Test questionnaire. The groups showed no significant difference in LM score after treatment. A positive correlation was observed between the LM and SNOT-20 scores. We concluded that adding oral acetylcysteine to amoxicillin-clavulanic acid, pseudoephedrine, and intranasal normal saline has no benefit for the treatment of subacute sinusitis.
