Metabolomic biomarkers of low BMD: a systematic review
2021
Due to the metabolic nature of osteoporosis, this study was conducted to identify metabolomic studies investigating the metabolic profile of low bone mineral density (BMD) and osteoporosis. A comprehensive systematic literature search was conducted through PubMed, Web of Science, Scopus, and Embase databases up to April 08, 2020, to identify observational studies with cross-sectional or case-control designs investigating the metabolic profile of low BMD in adults using biofluid specimen via metabolomic platform. The quality assessment panel specified for the “omics”-based diagnostic research (QUADOMICS) tool was used to estimate the methodologic quality of the included studies. Ten untargeted and one targeted approach metabolomic studies investigating biomarkers in different biofluids through mass spectrometry or nuclear magnetic resonance platforms were included in the systematic review. Some metabolite panels, rather than individual metabolites, showed promising results in differentiating low BMD from normal. Candidate metabolites were of different categories including amino acids, followed by lipids and carbohydrates. Besides, certain pathways were suggested by some of the studies to be involved. This systematic review suggested that metabolic profiling could improve the diagnosis of low BMD. Despite valuable findings attained from each of these studies, there was great heterogeneity regarding the ethnicity and age of participants, samples, and the metabolomic platform. Further longitudinal studies are needed to validate the results and confirm the predictive role of metabolic profile on low BMD and fracture. It is also mandatory to address and minimize the heterogeneity in future studies by using reliable quantitative methods. Summary: Due to the metabolic nature of osteoporosis, researchers have considered metabolomic studies recently. This systematic review showed that metabolic profiling including different categories of metabolites could improve the diagnosis of low BMD. However, great heterogeneity was observed and it is mandatory to address and minimize the heterogeneity in future studies.

Dual energy X-ray absorptiometry
2020
SummaryBased on the clinical, BMD, and TBS data of 2380 participants aged ≥ 60 which was gathered during the BEH program, stage II, we showed that MetS was positively associated with BMD, while a negative or no association was observed between MetS and TBS depending on the sex and the adjustment model.IntroductionThe results of previous reports in regard to the effect of metabolic syndrome (MetS) on bone health are not conclusive. This study aimed to evaluate the association between MetS with bone mineral density (BMD) and trabecular bone score (TBS) as an indicator of bone quantity and quality, respectively.MethodsUsing a cross-sectional design, this study was carried out based on the data collected during the BEH Program, stage II. MetS was defined according to NCEP-ATP III criteria. BMD (at the lumbar spine and the hip) and lumbar spine TBS were assessed by dual-energy X-ray absorptiometry device.ResultsThe data of 2380 participants (women = 1228, men = 1152) aged ≥ 60 were analyzed. In the fully adjusted regression models (including BMI), significant associations between MetS and mean BMD were observed across all locations in men (P values ≤ 0.001) and in the lumbar spine in women (P value = 0.003). In addition, the prevalence of osteoporosis (based on BMD) was significantly lower in those with MetS than those without MetS in both sexes, even after full adjustments (women, OR = 0.707, P value = 0.013; men, OR = 0.563, P value = 0.001). In contrast, in age-adjusted regression analyses, the prevalence of degraded bone microarchitecture (TBS ≤ 1.2) was significantly increased in those with MetS than those without, irrespective of the participants’ sex (P values < 0.05). The mean TBS was also negatively associated with MetS in women (β = − 0.075, P value = 0.007) but not in men (β = − 0.052, P value = 0.077), in age-adjusted regression models. However, after including BMI in the adjusted models, all significant associations between TBS values and MetS disappeared.ConclusionIt seems that a positive association exists between MetS and BMD, while MetS is either not associated or negatively correlated with bone quality as measured by TBS.

Inverse association between cigarette and water pipe smoking and hypertension in an elderly population in Iran: Bushehr elderly health programme
2017
The collected data in Bushehr Elderly Health (BEH) Program which had detailed the data on participants’ smoking status and habits, was analysed to investigate the association between smoking of both water pipes and cigarettes and hypertension in an elderly population. Three thousand elderly men and women who participated in the baseline assessment of the BEH Program—a prospective population-based study being conducted in Bushehr, Iran—were selected randomly through a multistage, stratified cluster sampling method. Systolic and diastolic blood pressures were measured twice using a mercury sphygmomanometer, and researchers asked participants about medical history of hypertension as well as history of cigarette and water pipe smoking. Researchers used binary logistic regression models to assess the association of hypertension and smoking, and found an inverse, statistically significant association between current smoking and hypertension (odds ratio (OR)=0.50 (95% confidence interval (CI)=0.41, 0.60)). The association remained statistically significant after controlling for age, education and body mass index (OR=0.54 (95% CI=0.45, 0.66)). Findings were consistent for cigarette and water pipe smoking by sex (all ORs were inverse and statistically significant). Both cigarette and water pipe smoking were associated with reduced hypertension among older people, but the strength of association was different between men and women and also between cigarette and water pipe smoking. The reasons behind the association as well as the differences observed need to be investigated through more comprehensive, longitudinal studies.

Blood Coagulation - drug effects
2015
In order to establish the efficacy and biosimilar nature of AryoSeven to NovoSeven in the treatment of congenital factor VII (FVII) deficiency, patients received either agent at 30 μg/kg, intravenously per week for 4 weeks, in a randomized fashion. The primary aim was to compare FVII:coagulation activity (FVII:C), 20 minutes after recombinant activated FVII (rFVIIa) injection, in the 2 groups. A secondary measure was self-reported bleeding. The median interquartile baseline range of the plasma level of activated FVII (FVIIa) activity in the 2 groups was 1.6 (1.1-14.0) IU/dL and 5.0 (1.1-25.5) IU/dL. All patients achieved levels of FVIIa (FVII:C) >30 IU/dL, 20 minutes after the injection of rFVIIa. Bleeding was similar between the 2 groups, with a comparable decrease in severity and frequency compared to the last month prior to treatment. AryoSeven is similar to NovoSeven in increasing postinjection FVIIa activity as well as in clinical safety and efficacy.

Biosimilar Pharmaceuticals - administration & dosage
2016
Introduction:
This study compared the efficacy of Aryoseven with Novoseven to control bleeding episodes in patients with hemophilia A with inhibitors.
Methods:
Sixty-six patients were randomized into 2 groups, with 4 consecutive block randomization. These groups received Aryoseven and Novoseven dosages of 90 to 120 μg/kg intravenously every 2 hours.
Results:
Median (interquartile range) level of factor VIII (FVIII) inhibitor in groups A and B was 15.0 and 19.0 Bethesda Unit (BU) preadministration. Bleeding onset in group A was 1246 ± 1104 minutes and in group B was 2301 ± 1693 minutes (P = .311). The Kavakli global response scores and treatment success rate was comparable in both the groups. The side effects in groups A (9.7%) and B (2.9%) were comparable.
Conclusion:
Biosimilar recombinant activated FVII is found to be as effective as Novoseven in the treatment of acute joint bleeding in patients with hemophilia with inhibitors. Its usage will decrease the gaps in hemophilia.

The effect of reflexology on pain intensity and duration of labor on primiparas
2011
Background : reflexology is an ancient, mild and non-invasive technique, used widely as one of the non-pharmacological methods for pain relief. The aim of this research was to determine the effect of reflexology on pain intensity as well as to determine the duration of labor in primiparas.
Methods : in 2008, a randomized clinical trial study was conducted randomly enrolling 120 parturient women with low risk pregnancy into three groups in Shahid Akbarabadi Hospital, Tehran, Iran. The first group received 40 minutes of reflexology at the beginning of active phase (4-5 cm cervical dilatation). Emotional support was offered for the second group in the same stage of pregnancy and with the same duration. The third group received only routine care during labor. Pain severity was evaluated with visual analogue scale (0 to 10 cm). In all groups, pregnant women were asked to evaluate the severity of pain experienced before and after intervention and also at cervical dilatations of 6-7 cm and 8-10 cm respectively. Data were collected through the numerical pain scale.
Results : pain intensity at all the three stages of cervical dilatation was significantly lower in the reflexology group. During the 4-5 cm dilatation stage, women in the supported group reported less severe pain compared to those receiving routine care, but no significant differences at the later stages of labor. This indicates that reflexology could decrease the duration of first, second and third stages of labor.
Conclusion : our findings showed that reflexology can be useful to decrease the pain intensity as well as dura-tion of labor.

Vitamin d deficiency in healthy male population: results of the Iranian multi- center osteoporosis study
2010
The prevalence of vitamin D deficiency and its causative factors has been estimated more frequently in elder population, women, and patients with osteoporosis in different countries, but this issue is less defined in male population within different age groups especially in Asian countries. Therefore, we studied the role of effective factors in vitamin D deficiency and its prevalence in Iranian healthy men.
This study was a multi center and carried out in five metropolitans in Iran. Serum 25 Hydroxy vitamin D and other biochemical variables were determined in 2396 healthy men in late winter of 2001.
68.8% of participants suffered from vitamin D deficiency. Vitamin D levels were the highest in Bushehr (n= 111, 40.3%) (P< 0.05) and between Shiraz and Tabriz, Shiraz had the better values (P< 0.05). Tehran had the highest prevalence of vitamin D deficiency (n= 380, n= 85.7%). Geographical zone independently predicted vitamin D status (P< 0.05). There was not any association among age (r= 0.035, P> 0.05), physical activity (r= 0.023, P> 0.05), and exposure of face & hands to sunlight (r= 0.022, P> 0.05) with vitamin D levels.
Prevalence of vitamin D deficiency in Iranian male population is high, considering Iranian cultural and geographical zones, food fortification and life style modification is recommended.

•Conducting RCT to examined acupressure on relief childbirth-related pain.•Acupressure on BL32 points can be an effective method to reduce labor pain.•Acupressure on LI4 point can be an effective method to reduce labor pain.•Acupressure on BL32 points can be more effective than acupressure on LI4 point.
This study examines and compares the effect of LI4 and BL32 acupressure with each other and control group on labor pain and delivery outcomes.
In this randomized controlled trial, 105 primiparous women in active phase of first-stage of labor were equally assigned to two experimental groups [acupressure on LI4 (n=35) or BL32 (n=35)] and a control group (n=35).
The experimental groups received routine labor care and acupressure in LI4 or BL32 points in three cervical dilatations (4–5, 6–7, and 8–10cm). The control group only received routine labor care.
Pain was assessed by numerical rating scale in three cervical dilatations, before and after intervention. Type of delivery (cesarean, vaginal or operative delivery) and neonatal Apgar score were considered as delivery outcomes, these data collected by a check list. Data were analyzed using Repeated Measurement, ANOVA, Chi-Square, Kruskal-Wallis, and Mann-Whitney tests.
Pain reduction was significantly greater in LI4 and BL32 groups compared with control in all periods of study. Also, acupressure on BL32 point was superior to LI4 point in pain relief in the first and second but not third intervention. No statistically significant difference was observed in terms of delivery outcomes.
Acupressure on BL32 and LI4 points are effective in reducing labor pain compared to control group with a slight superiority for BL32 points. Acupressure on these points could apply for relief pain in labor as an inexpensive and easy to administered method.

The prevalence of diabetic peripheral neuropathy and related factors
2011
Diabetic peripheral neuropathy (DPN) accounts for 80% of diabetic foot ulceration; therefore neurologic examination plays a critical role in screening at risk patients. Our objective was assessment the prevalence of DPN and related factors based on clinical findings.
This cross-sectional study was conducted on 124 diabetics who were randomly recruited from Diabetes Clinic of Dr. Shariati University Hospital (Tehran/Iran) in 2004. After gathering demographic data and blood sampling for fasting blood sugar (FBS), the questionnaires United Kingdom (UK), Michigan, Diabetic Neuropathy Score (DNS), and 10-g monofilament testing were administered. Analysis tests were chi-square, pearson correlation and logistic regression.
The patient's age ranged 17-75 years; with 44% male. Ninety one percent suffered from type two diabetes and the mean duration of diabetes was 10 years. The mean FBS level was 181.5 mg/dl. While the prevalence of DPN based on Michigan, DNS, and monofilament testing was about 32-38%, some 54% were diagnosed by UK test. Tingling in the lower extremity was the most frequent complaint (42%). The strongest linear correlation was reported between Michigan and DNS (r= 0.7), and then between monofilament test and DNS (r= 0.6). The age > 50 years, length of diabetes > 10 years, and FBS >200 mg/dl were the main risk factors for DPN based on DNS.
It seems that the combination of Michigan and monofilament test can provide an accurate screening tool for detecting DPN. In addition, tight glucose control, regular assessment of the lower extremity, and to educate diabetics is urged in elderly diabetics, longer duration of diabetes, and those with high FBS.

Hypertension is a modifiable risk factor for cardiovascular disease, but its aetiology has not been fully elucidated. Recently, attention has been focused on the direct relations of plasma homocysteine (Hcy) to blood pressure (BP). The purpose of this study was to determine the relationship of Hcy with BP and other cardiovascular disease risk factors. This population-based study was a part of the Cardiovascular Risk Factors Survey and has been designed and conducted based on the methodology of the MONICA/WHO Project. A total of 1214 people aged 25–64 years were recruited using cluster sampling and assessed regarding standardized methods. BP was measured in seated position after a 10-min rest period. Blood samples were gathered and analysed according to standard methods. Variables were assessed in 1191 participants (416 men; 775 women). Mean age was higher in hypertensives compared to normotensives (
P
<0.001). Mean Hcy was higher in hypertensives, but significant only in men (
P
<0.031). Concurrent effects of Hcy, folate and vitamin B
12
on hypertension indicated that Hcy acts as a risk factor and folate and vitamin B
12
as protective factors; however, after adjustment, just vitamin B
12
remained as a protective factor. Although we detected a simple correlation of Hcy with BP in Iranian adults, this relationship was no longer significant after applying an adjustment. In light of our observations, it is likely that the increased Hcy levels reported in hypertensive persons are concomitant rather than a precursor of hypertension.
